On April 12, 1981 the Space Shuttle Columbia became the first shuttle to orbit the Earth. In this gorgeous time exposure, flood lights play on the Columbia and service structures (left) as it rests atop Complex 39's Pad A at Kennedy Space Center in preparation for first launch. Flown by Commander John W. Young and Pilot Robert L. Crippen, Columbia spent 2 days aloft on its check-out mission.
